United States Patent O U.S. Cl. 194-59 20 Claims ABSTRACT F THE DISCLOSURE The disclosure relates to a coin lock mechanism which has a lock bolt movable in a housing and a latch interacts between the housing and lock bolt to prevent movement of this lock bolt in the absence of a coin in an operative position. The presence of a coin cams the latch means to an invalidated position to permit movement of the lock ibolt. A pivoted coin chute in the housing is a part of the latch means and it is pivoted away from the lock bolt to invalidate the latch means. A latch lever is pivoted on the coin chute and spring urged toward a positionsuch that upon return movement of the lock bolt only the latch lever pivots and the coin chute need not pivotally move away from the lock bolt to permit this return movement. Cocking and tripping levers are also pivoted on the coin chute. Spring means causes the cocking and tripping levers to interengage at second latch means and the cocking lever is cocked upon movement of the lock bolt and is then tripped upon return movement of the lock bolt so as to actuate a meter register registering the number of coin operated actuations of the lock mechanism.

Cross references This application is a continuation-in-part of my application Ser. No. 570,267 filed Aug. 4, 1966, now Patent Number 3,397,765 entitled Coin Operated Lock.

Background of the invention Coin operated locks have previously been used, especially in transportation terminals, wherein lockers may be locked by inserting a coin or coins of the proper denomination and then turning a key with the coins permitting this turning to lock the lock and locker. The key may then be withdrawn to lock a persons luggage or the like within this locker. When the person returns, he uses the key to unlock the locker to retrieve his luggage and the key is again captive in the lock. The coins provide a means to actuate the lock and thus a fee is collected for the temporary use of the lockers. Such coin operated lock may be of the type of my prior Patent No. 3,249,197.

Other coin operated locks have been provided for dispensing machines to unlock a door or the like to permit access to an article being dispensed for a fee..

Still other coin operated locks are known wherein a coin of the proper denomination is required before a key may be used to actuate the lock. This may be in a checking locker wherein the lock permits free service by return of the coin after the locker is unlocked. The coin, therefore, serves as a deposit to assure safe return of the key. The present invention permits a coin operated lock to be used for all three of the above-mentioned purposes and the first and third uses above may be provided in a single lock mechanism wherein the lock may be converted in only a few seconds from a free service lock to one requiring payment of a fee. Free service locks requiring temporary use of a coin, which is later returned to the operator is found in my prior Patent No. 3,233,713.

In many of the prior coin operated locks, it is possible 3,44l,1 18 Patented Apr. 29, 1969 ICC to use a coin to lock the lock and obtain the key and also to obtain return of the coin thus enabling wrongdoers to steal the key. In other prior art locks it has been possible to manipulate the locks without use of a coin and thus obtain free service where a fee normally should have been collected by the use of a coin. In still other prior art locks a cumbersome and complicated mechanism has been required to collect use of the coin or coins and to attempt to minimize the stealing of keys or wrongful return of the coin in a fee paid lock. In other prior art locks it has been very difiicult to change the denomination of the coin or coins necessary to operate the lock and in many cases it has been necessary to send the locks back to the factory or to disassemble a considerable part of the lock mechanism in order to change the denomination of coins.

Summary of the invention The invention may be incorporated in a coin operated lock mechanism having, a housing, a lock bolt movable in said housing between first and second positions, one of said positions being a locked position of said lock bolt cooperating with a first member and the other being an unlocked position, actuator means to move said lock bolt, coin retention means to retain a coin in an operative position in said housing, and having first latch means interacting between said housing and said lock bolt to prevent movement of said lock bolt from said first to said second position in the absence of a coin in said operative position, wherein the improvement comprises, in combination, first and second members included in said latch means, means mounting said latch means first member for movement in the housing, means mounting said latch means second member on said first member for movement relative thereto, a cam follower connected to act on the latch means, the coin retention means establishing a coin in the operative position and the coin camming said cam follower to invalidate the latch means as the actuator means is moved and the lock bolt is moved from the first toward the second position along a first path to thus permit complete movement of the lock bolt from the first to the second position, said camming action moving said first member relative to the housing to invalidate the latch means, first spring means acting on said second member, and return movement of the lock bolt returning from the second position to the rst position moving said latch means second member against the urging of said spring means to allow said return movement without movement of said first member relative to the housing.

Other objects and a fuller understanding of this invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIGURE 9 is a sectional view on line 9-9 of FIG- URE 5; and

FIGURE l() is a top view of the coin chute of FIG- URE 6.

The figures of the drawing illustrate a preferred embodiment of the invention butit is to be understood that the invention is not limited by the hereinafter described preferred embodiment but only by the claims appended hereto.

The lock mechanism 15 is described as a coin operated lock and it will be understood that wherein the word coin is used it embraces the use of a token or check as well as an actual coin having monetary significance and issued by some government.

The FIGURES 1-10 of the drawings generally illustrate the construction and operation of the lock mechanism 15. This mechanism is mounted in a housing or case 16. The lock mechanism 15 is operable by a coin 17 and also in this preferred embodiment is operative by a key 18. The lock mechanism 15 is thus coin and key operated and may be mounted on the inside surface 20 of a locker door 21. The locker door is hinged by a hinge, not shown, at the left side of FIGURE 2 to a door frame 23. The lock mechanism 15 also has a movable lock bolt 25 movable into locking cooperation with an aperture 26 in a lock post 27, a part of the door frame 23 of the entire locker.

The lock bolt 25 is shown as being slidable in the housing 16 and is movable between first and second positions. The first position is that shown in FIGURE 1 and the second position is with this lock bolt 25 completely extended through the aperture 26 into the lock post 27, partly shown in FIGURE 4. One of these two positions may be a locked position of the lock mechanism 15 and in this preferred embodiment the second position is the locked position with the outer end of the lock bolt 25 close to the lock post wall 28. In this lock mechanism 15 a coin 17 is required in an operative position 17a as shown in FIGURE l, in order to actuate the lock mechanism. In this case a coin in the operative position is required in order to move the lock bolt 25 into the lock post 27. However those skilled in the art will readily understand how a coin may -be used in the operative position to unlock the lock, for example, in dispensing machines and the like.

Actuator means 29 is movable to actuate the lock bolt '25. Briefly this actuator means includes the key 18, a key cylinder 30 and an actuator lever 31 with an actuator pin 32.

The lock bolt 25 includes a rear plate 35 and a front plate 36 spaced apart to receive the coin 17. An over-center spring 37 engages the housing 16 and the lower end of actuator lever 31 to urge the lever into each of the first and second positions from an intermediate position. An S-shaped over-center spring 38 urges the lock bolt toward each of the first and second posiions from an intermediate position.

A first member 40 is mounted for movement in the housing 16. In this preferred embodiment the first member 40 is a coin chute which includes front and rear plates 41 and 42 spaced apart to receive a coin therebetween. This coin chute 40 is pivoted at 43 to be arcuately movable relative to the housing 16. A coin entry 45 is provided in the front edge 46 of the door 21 to provide access to the coin chute 40. A coin 17 upon being inserted through the entry 45 rides down a slope of a spacer 47 between the front and rear plates 41 and 42 and passes a magnet 48 to catch ferrous slugs. Such a coin 17 will drop into an operative position 17a in the lock bolt 25.

First latch means 50 is provided between the lock bolt 25 and the housing 16. The first latch means 50` includes an abutment 51 on the top edge of the front plate 36 of the lock bolt 25 and also includes a second member 52 movable relative to the coin chute 40. In this preferred embodiment second member 52 is a latch lever 52 pivoted on the coin chute 40. The first latch means 50 prevents movement of the lock bolt 25 from the first position of FIGURE 1 completely to the second position thereof in the absence of a coin in the operative position 17a. The latch lever 52 has first and second sides 53 and 54. A spring 55 is a first spring means and urges the latch lever 52 second side 54 into engagement with an abutment 56 on the coin chute 40. Thus the abutment 56 is a part of the first latch means by preventing counterclockwise movement of the latch lever 52 as the lock bolt 25 is attempted to be extended from the first toward the second position.

A coin receptor 57 is a flat plate longitudinally slidable inside the lock bolt 25 and retained between the front and rear plates 36 and 35 thereof. A lock pin 58 may be inserted in any one of a plurality of lock pin holes 60 of the lock bolt 25. This permits ready conversion in the field to change the lock for many different combinations -of coins or a token. Thereceptor 57 has an upper surface 59 which slopes downwardly toward the outboard end of the lock bolt 25. Coin retention means are provided between the sloping surface 59 and the lock pin 58 to receive a coin of the proper denomination therebetween and establish the top-most arc vof such Acoin in the operative position. Where two or more coins are used of the same or different sizes, the top-most arc of theupper coin is that which is'established in the operative position 17a. The plurality of lock pinho'es are provided in order to change the denomination of the coin or the coins required to actuate the lock. One or two coins of various denominations may be made to provide many different combinations for denominations between Scents and cents. Also a token, for example, of a diameter between that of a nickel and a quarter may be sold for any amount of money so that the lock mechanism 15 will be able to be set for actuation by any amount of money. As shown in FIGURE 1, the coin 17 is caught and held in the operative position 17a by being trapped between the sloping surface 59 and a surface on the lock boit 25, namely the lock pin 58 at a point just below the maximum diameter of the coin. This is the coin reteniion means and permits coins or slugs of smaller diameter to pass through without being able to actuate the lock.

A lifter or cam follower 61 is provided as a lower eX- tension of the spacer 47 in the coin chute 40. This cam follower 61 has a lower surface 62 and a front sloping surface 63. The actuator means 29 is connected to actuate the lock bolt 25. To this end the actuator pin 32 on the actuator lever 31 is engaged in a slot 66 in the rear plate 35 of lock bolt 25. This slot 66 is generally V-shaped and has a first slot portion 67 which is generally vertical and a second slot portion 68. The fact that the second slot portion 68 has length in a longitudinal direction of the lock bolt 25, provides a lost motion means in the movement of the lock bolt 25 relative to movement of the actuator means 29. The key 18 fits in the key cylinder 30 and the inner end of cylinder 30 fits into a socket 73 in the actuator lever 31 to turn this lever 31 by, turning tbe key 18. The key cylinder 30 is shown removed in FIG- URE 1 for clarity in order to show the socket 73.

The actuator means 29 also actuates the coin receptor 57. The actuator lever pin 32 not only engages slot 66 in the lock bolt 25 but also engages a slot 78 in the coin receptor 57. This slot 78 is generally vertical and is aligned with the first slot portion 67 in the first position of the lock bolt 25, as shown in FIGURE l.

A meter 80 is mounted in the upper corner of the housing 16 and this may have a register 81 viewable through an aperture in the front of the door 21 to register the number of coin operated actuations of the lock bolt 25. This meter 80 may be actuated by an oscillatable actuator lever 82 in turn actuated by cockable means 83 on the coin chute 40. This cockable means 83 includes a cooking lever 84 and a tripping lever 85. Each is pivoted on the coin chute 40 and springs 86 act to urge two adjacent ends of the cocking and tripping levers 84 and 85 toward each other. A hook 87 on the tripping lever 85 is engageable with a hook 88 on the cooking lever 84, see FIGURE 4, under urging of the springs 86 to constitute second latch means 89 interacting between the cocking lever 84 and tripping lever 85.

A first or lower end on the cocking lever 84 has a cam follower 91 and a first or lower end on the tripping lever 85 has a cam follower 92. The cam follower 92 has a holding surface 93 and a tapered cam surface 94. A cam 96 is provided on the lock bolt 25 and as best shown in FIGURE 3 this cam 96 is a plate xed to the inner end of the lock bolt 25, on the rear plate 35, and is bent at right angles to the lock bolt 25 to also act as a guide for guided longitudinal movement of the lock bolt 25. Cam 96 has a rear edge 97 and a forward edge 98.

An owners lock cylinder 101 may be journalled in a barrel 102 fixed in the housing 16. This cylinder may be actuated by an owners key 103. Turning the key 103 and lock cylinder 101 will turn an owners cam 104 which is partly shown in FIGURE 1 and more completely shown and described in my co-pending application Ser. No. 570,267. The owners cam 104 has a portion to engage a cam follower 105 fixed on the coin chute 40. In one position of the owners cam 104, the cam follower 105 will be actuated to lift the coin chute 40 to the Iposition shown in 'FIGURE 4. In this position free service operation of the lock mechanism may be had because the latch means 50 is invalidated by the lifting of the coin chute 40. This free service position of the owners cam 104 may be used in recreation terminals for example, wherein free service is desired for checking lockers at certain times.

Operation FIGURES 1 through 4 illustrate the operation of the lock mechanism 15 in its use as a coin and key operated lock. The coin 17 may be inserted through the coin entry 45 to fall through the coin chute 40 and into the lock bolt 25. A coin of smaller diameter than the proper denomination will pass completely through the coin retention means 58-59 and will not permit the lock 15 to be actuated. A coin of the proper denomination will be caught between the coin retention means 58-59 so that it is in the operative position 17a. The key 18 is captive in the lock cylinder 30 when the lock bolt 25 is in the first position, shown in FIGURES 1 and 2. Accordingly, the key 18 may be used as a handle to pull open lthe locker door 21. A person may then insert his luggage or parcels in the locker and then insert the coin which falls to the operative position 17a. Next the door 21 may be closed and then the lock mechanism may be locked. The actuator means 29 may be moved through a path such that the actuator lever 31 is rotated clockwise 90 degrees from that shown in FIGURE 1. The socket 73 will accordingly rotate 90 degrees clockwise to a horizontal position. The actuator pin 32 engages both the slot 78 in the receptor 57 and the first slot portion 67 on the lock bolt 25. Accordingly, both the lock bolt 25 and receptor 57 move together substantially the same distance. The coin 17 moves with the lock bolt 25 because it is held by the coin retention means 58-59. Accordingly, it engages the front sloping surface 63 of the cam follower 61 and then rides on the lower surface 62 of this cam follower 61. This causes the coin chute 40 to pivot upwardly so that the latch means 50 is rendered inoperative or is invalidated. If the coin 17 is not the proper denomination, and is too large in diameter and has somehow been forced through the coin entry 45, then this will attempt to lift the coin chute 40 so far that it will engage the inside surface 107 of the housing 16 and thus will not permit complete movement of the lock bolt 25 from the first to the second position. However, where the coin 17 is of the proper denomination, the actuator lever 31 may be continued to be turned through its 90 degree arcuate movement, in which position the actuator pin 32 will have moved both the lock bolt 25 and coin receptor 57 substantially the same distance so that lock bolt 25 is in its extended second position of FIGURE 4. The spring 38 gives a snap action to the lock bolt 25 after it passes an intermediate point of travel to rapidly extend this lock bolt and to prevent pry-back of the lock bolt. The coin 17 is preferably retained between the sloping surface 59 and the lock pin 58. The actuator pin 32 will be at the bottom of the slot 78 and iirst slot portion 67. The outboard end of the lock bolt 25 will lhave extended into close proximity to the lock post wall 28. The lock mechanism 15 will now be locked, the socket 73 will be horizontal and the key 18 may now be removed because it is no longer captive in the lock cylinder 30.

After the user has returned, he may again insert the key 18 and turn the key counter-clockwise 90 degrees to the position of FIGURE l. In so doing the very first movement does not move the lock bolt 25 to the left but instead moves only the receptor 57. This is because the S-shaped overcenter spring 38 holds lock bolt 25 in the outward position while receptor 57 is returned. FIG- URE 4 shows the lock bolt 25 in the fully extended position and shows receptor 57 in its position of being partially retracted relative to housing 16, and in fact completely retracted relative to the lock bolt 2S. This is permitted because the second slot portion 68 is a lostmotion means. As the actuator lever 31 is turned counter-clockwise from the horizontal position of socket 73 to the position of FIGURE 1, the actuator pin 32 does not move the lock bolt 25 until pin 32 reaches the left end of the second slot portion 68. In the meantime, actuator pin 32 does engage the left side of slot 78 because it is closely received therein. Accordingly, it moves receptor 57 to the left and this separates the sloping surface 59 sufficiently from lock pin 58 so that the coin 17 drops to the outer end of the lock bolt 25. From here it may drop into the lock post 27 to a coin collection receptacle. When actuator pin 32 engages the left end of second slot portion 68, as viewed in FIGURE l, then lock bolt 25 lwill be withdrawn toward the rst position of FIGURE 1. During the nal portion of this return movement, the outer end of the actuator lever 31 engages a cam follower 77 on the lock bolt 25 to complete the retraction. Also during the nal portion of this return movement, the receptor 57 slows down in its leftward movement relative to the leftward movement of lock bolt 25 so that receptor 57 returns to a position relative to lock bolt 25, as shown in FIGURE 1, whereat the proper denomination coin 17 would again engage the coin retention means 58-59.

If no coin or no coin of the proper denomination has been put into the lock mechanism 15, the lock bolt 25 may not be completely extended, and because the key 18 is captive in the key cylinder 30 until it gets to the horizontal position, the key 18 may not be withdrawn and hence a person is not able to lock his belongings in the locker 21. The first latch means 50 is the reason why the lock bolt 25 may not be completely extended in the absence of a coin 17. As the lock bolt 25 is attempted to be extended, the abutment 51 on the lock bolt 25 will engage the rst side 53 of the latch lever 52 which is a second member of this rst latch means 50. The second side 54 of the latch lever 52 will engage the abutment 56 to prevent the extension of the lock bolt 25. As stated above, however, with a coin of the proper denomination in place in the coin retention means 58-59, the camming action of the cam follower 61 riding up on the coin 17 will cam the coin chute 40 upwardly to invalidate the first latch means 50.

During the nal portion of the retraction or atleast upon complete return movement of the lock bolt 25 from the second or extended position to the first position shown in FIGURE 1, the rear edge 97 of the cam 96 has acted on the cam follower 91 of the cocking lever 84 to cock the cockable means 83 and hence inter-engage the second latch means 89. This will be as shown in FIGURES 1 and 4. After the lock bolt 25 has been extended to the second position, as shown in FIGURE 4, the iirst part of the return movement of the actuator lever 31 counter-clockwise returns the receptor 57 as shown in FIGURE 4 and as stated above. When the lost motion means 32-68 has been taken up, the lock bolt 25 starts to retract. As it does the holding surface 93` on the cam follower 92 of the tripping lever 85 rides off the forward end 98 of the cam 96. At this point the tapered cam surface 94 co-acts with the forward edge 98 of cam 96 to rapidly swing the tripping lever 85 as a spring or second spring means 111 rapidly pivots the coin chute 40 downwardly. This trips the second latch means 89 and springs 86 to move the cooking lever 84 counter-clockwise as viewed in FIGURE 4. A fork 112 on the cocking lever 84, as shown in FIG- URES 3 and 4 actuates the actuator lever 82 on the meter 80. i

During this rapid pivotal downward movement of coin chute 40 by spring 111, the lower end of the latch lever 52 drops into a notch 110 on the front plate 36 of the lock bolt 25. The latch lever 52 is not cammed out of the notch 110 during return movement of the lock bolt 25, instead the latch lever 52 pivots on the coin chute 40 against the urging of the spring 55 and accordingly the second side 54 of the latch lever 52. swings away from the abutment 56. By this means the coin chute 40 does not need to pivotally raise during return movement of the lock bolt 25. This is a safety feature so that a Vandal is not able to hit the bottom of the door an upward blow to bounce the coin chute 40 upward, with the door open, so the vandal can recover both the money and the key.

The register 80 being actuated by the rapid downward pivotal movement of coin chute 40 assures proper and accurate actuation of this register 80. The spring 111 rapidly urges coin chute 40 pivotally downwardly to smartly and effectively actuate the lever 82 for positive actuation of this meter 80. Also it will be noted that the meter 80 actually registers only the number of coin operated actuations of the lock bolt 25 and does not record the free service actuations of the lock bolt 25. The reason is that during free service, the owners cam 104 keeps the cam follower 105 and coin chute 40 urged upwardly to invalidate the first latch means 50 and hence there is no downward pivotal movement of the coin chute 40 to actuate the meter 80. Accordingly, the meter 80 is able to give an accurate count of coin actuated operations so that a supervisor may tell the proper `amount of money which should have been collected by the coin actuations of that particular lock mechanism in that particular locker 21. This provides a means of checking the amount of money which the coin removal attendant is supposed to turn in and hence kavoids the temptation for dishonesty on the part of this attendant.

The key 18 is captive in the key cylinder 30 for all positions except the position corresponding to a horizontal socket 73. This means that the key 18 cannot be removed except when the lock mechanism 15 has been properly actuated to the extended position of the lock bolt 25. This prevents stealing the key 18 and obtaining return of the coin 17.
